Phoenix, Arizona, is known for its desert beauty, sunny skies, and diverse seasons. But with each seasonal shift comes an invasion of unwanted guests. This seasonal pest guide will help Phoenix residents understand what pests to expect throughout the year. Whether you’re facing an ant trail in spring or scorpions in summer, pest control services become essential for protecting your home. At T J Pest Control, we offer expert pest control tailored to Arizona’s unique environment.

Spring – Swarms, Nests, and Waking Threats
As temperatures rise, pest activity begins to spike.
Ants are usually the first to appear. They search for food and water, forming long trails across kitchens and patios. They often enter homes through cracks, especially after a rainy day.
Termites also become active in spring. Swarmers fly out to start new colonies. These flying termites can cause structural damage if left untreated.
Spiders reemerge after hiding during winter. Black widows and wolf spiders are common in garages, sheds, and wood piles.
Rodents might still linger. Roof rats and mice that find shelter in the winter may stick around unless properly removed.
What to do:
- Seal cracks and crevices.
- Clear wood piles and debris.
- Schedule a spring inspection with a pest expert.
Summer – Heat Drives the Infestation Deeper
Phoenix summers are scorching. Unfortunately, pests don’t take a vacation.
Scorpions are a top concern. They hide in dark, cool places during the day. At night, they hunt for insects. Their stings can be painful and dangerous for kids and pets.
Cockroaches love the heat. American and German cockroaches infest kitchens and bathrooms looking for water.
Mosquitoes are active near standing water. Even small puddles or birdbaths can become breeding grounds.
Crickets, while harmless, can become a noisy nuisance in backyards and patios. Their presence also attracts scorpions.
What to do:
- Use yellow light bulbs outdoors to deter insects.
- Keep shrubs and grass trimmed.
- Eliminate standing water.
- Consider monthly pest control treatments.
Fall – Pest Invasions Seeking Warmth
When the desert cools down, pests look for warm spaces.
Rodents have become a bigger issue. Mice and rats seek shelter in attics and walls. You may hear scratching noises or see droppings.
Spiders follow their prey indoors. Cooler weather means more indoor webs, especially in corners and under furniture.
Crickets again surge in the fall, especially after the monsoon season. Their loud chirping and sudden jumps can be annoying.
Beetles, especially stink bugs, look for cozy homes. While they don’t cause damage, they emit an unpleasant odor if crushed.
What to do:
- Store pet food in sealed containers.
- Block roofline gaps and attic vents.
- Check weather stripping around doors.
- Schedule an autumn checkup with T J Pest Control.
Winter – Quiet Months, But Not Pest-Free
Though winter is quieter for pests, it’s not completely pest-free in Phoenix.
Rodents stay hidden in walls and insulation. They chew on wires, creating fire hazards. Rodents reproduce quickly, so early detection is key.
Silverfish thrive in bathrooms and laundry rooms. These tiny insects feed on paper and fabric.
Cockroaches, especially German cockroaches, stay active indoors. They prefer warmth and moisture.
Spiders continue to linger in attics and basements. While not aggressive, they still create messy webs and can startle homeowners.
What to do:
- Deep clean storage areas.
- Reduce moisture in bathrooms and kitchens.
- Set traps to monitor activity.
- Call professionals for safe removal.

How Seasonal Changes Affect Pest Behavior
Phoenix’s weather creates specific challenges:
- Warm winters keep some pests active year-round.
- Spring rains attract insects like ants and termites.
- Summer heat drives pests indoors for water and shade.
- Fall becomes the transition season for overwintering pests.
Understanding these shifts helps you stay one step ahead.

Some pests only need a crack the size of a dime to enter your home.
Here’s where they often sneak in:
- Gaps under garage doors
- Broken window seals
- AC unit holes
